UNITED- STATES PATENT orrlcn. l

W'LLIAQ; F, 0F HEMATITE, MISSOURI.

T0 all whom #may concern l Be it known that I, WILLIAM F. DONNELL, a citizen of the United States, residing at Hematite, Missouri, have invented a certain new and useful Improvement in Milk-Cans, ,of which the following is a full, clear, and exact description, such as will enable others Skilled in the art to which it appertains to make and use the same, reference being had to the accompanying-drawings, forming part .of this specilication, in whlch- Figure 1 is a side elevational v iew of a` milk can of my improved construction, parts thereof being broken away and` the lower {portion 4being shown in vertical section.v Fig. 2 is an enlarged detail section taken approximately on the line 2-2 of Fig. 1. Fig. 3 is a detail elevation of the upper portion of the can, and showing one of the hooks used for attaching the cover tothebody of y the can. Fig. 4 is a vertical section 'taken on the line 4-4 of Fig. 3.

This invention relates generally to new and useful improvements in cans particu' larlyintended for containing milk during transportation and storage, although cans .of my construction can-be advantageously used for containing any-liquid or semi-'liquid' tion of the can body; to provide a 'cover *for the body, and to arrange on'said cover a gasket for the purpose of providing a perfect air and water-tight joint between-the can body and cover `when the latter is proyerly applied; to form the lower end of' the ody which can be manipulated so as to draw the cover into close engagement with the upper end of the body, thereby compressing 5. thehga'sket equall at all .points between the cover'and the bo and consequently forml' specification ofeLetm-s raten.

ing an air and water-tight joint, which is a particularly desirable feature in large cans.

To the above purposes my invention consists in certain novel features of construction and arrangement of parts hereinafter .more fully described and claimed. l

Referringby numerals to the accompanying drawings: 1 designates the body of thev can which is preferably cylindrical and formed from a single piece of sheet metal .drawn or pressed so as to forml a seamless receptacle in the form of 'a cylinder having the same internal diameter throughout. its

length and with va perfectly VVsmooth, un-4V broken interior surface. I

The bottom 2 of the can is preferably made convex, and' that portion of the body ofthe canbetween thebottom 2 and the A wall is roundedas designated by '3 in order that the lower endof one can will readily adjust itself lto the seat formed fin the top or coverco'f an adjacent `can when the cans are arranged one `onltop of the otherduring storage/ or while irtransit.

- The upper end if the body of the can is provided with an annular 'bead' 4, 'the same being preferably wired,` as shown. 5 designates plates which arev appliedto the outersurface of -t-heybody of the can at diametrically 4opposite points, and formed on the uppenends of these plates are hooks 6 adapted to be 4engaged by the cover-.attaching means. Formed integral with the lower portions of the plates 5 are .perforated ears' 7 from whic'h are suspended loops -8 which perform. the. function of handles whereby .the `can can be' readily lifted and carried.

kFormed integral with each plate andprefverably at apoint between the ears 7 -is aloop 9 whichis adapted to coperate witha portion ofthe cover-'attaching means .heremafter described.

. The` plates 5 are preferably fused` or sweated onto the 'body-of the can, vthereby avoiding the use-of rivets and the formation of -rivet holes through the can body, and

after said-plates have been .properly applied v to the can body the entire structureis preferably aplated or coated with suitable-,nonrusting material.

10. designates'thefcan cover which xis preferably constructed of a single sheet of metal,

lwith its edge 11 bent arounda heavy wire 12 tofform a marginal bead. That .portion of the metal forming the cover `lever 18.

y of the can body,

the bead i bearing against the under side Loeaeev adjacent to the bead `which is bent upwardly as designated by 13 to form an annular ribwhich is substantially of inverted U-shape in cross section, thereby forming a seat for the bead 4 on the top of the can body when the cover is applied thereto. Arranged within this annular rib 13 is a .gasket 14 of `rubber or analogous material, which, when compressed under the downward pressure ap lied to the cover, forms an air and liqui tight ,joint betweenl the cover and the can body. The main body portion of the cover 10 occupies a plane substantially below the plane occupied by the top of .the annular rib 13,.and thus a shallow seat is formed in the central portion of the cover for the' lower end of an adjacent can when the same are arranged one on top of the other during storage or transit (see dotted lines -a- Fig. 2). v

Suspended from the-wire 12 in the beaded edge of the cover 10 is a link 15, and pivotally carried by the lower end thereof is a hook 16, the lower end of which is adapted to engage either one of the hooks 6. Arranged on the edge of the cover 10 directly opposite from the link 15`and suspended from the wire 12 is a link 17, the lower end of which is bifurcated, and pivotally mountf ed therein is the bifurcated upper eifd of a The lower end of this lever is providedwith an opening 19 adapted to receive either one of the loops 9 when t-he cover is properly positioned and locked to the can body.

' Pivotally carried upon' a pin 2O that is seated in the upper portion of the bifurcated upper end of the lever 18 and in a plane above the pivot pins between the link 17 and lever 18, is a hook 21, the lower end of which is adapted to engage either o-ne of the hooks 6.

I have described my improved can as being particularly intended for use in the ship ment and storage of milk, but it will be readily understood that cans constructed substantially as herein shown and described can be advantageously utilized in the transportation o sea foods, such as fish, oysters and the like, and said can can be also used for the shipment of garbage or for any product which vnecessitates the use of an air and liquid-tight receptacle.

. When the'cover is applied to the can, the hook 16 is engaged beneath the hook 6 on one side of the can and the cover is now manipulated downward on to the upper end with the upper portion of of the gasket 14.

The lever 18 is now manipulated so that,

its lower end is uppermost, as shown bydotted lines in Fig. 2, and when so positioned the pivot pin 20 occupies a plane below the pivot pins between the link 17 and lever 18,

With the parts so positionedy the lower end.

an air and water-tight joint between the i cover and can body. v l

The lower end of the lever 18 is moved into, a position against the lower portion of the plate 5 with the loop l of said plate projecting through the opening 19, and theglever is locked into this position by the application of a sealing wire, or like device.

'lhe body of the ocan is imperforate and seamless inasmuch as it is made from a single piece of sheet metal drawn to proper shape and the entire structure is entirely devoid of rivets or like fastening devices.

The can covers can be readily placed in or removed from position, and where a number. of the cans are piled up for storage or for transportation, said cans can be readi ily nested, one on top of the other.

The body of the can is of the same diameter throughout its length, thereby facilitating the cleansingv of the interior, and when said cans have been tho-roughly washed they can be quickly dried and rendered sanitary by being placed in the open air in such positions that the suns rays can enter the interior of the cans.

It will be understood that mino-r changes in the size, formand construction of the various parts of my improved can may be readily made and substituted for those herein shown and described without departing from thespirit of my invention, the scope of which is set forth in the appended claims. 4
